Why Concept Mapping?
Rote Learning (Memorization)
vs.
Meaningful Learning

3. Meaningful Learning
Learning occurs when new knowledge is added to an existing knowledge structure
Knowledge is constructed; NOT discovered
Three requirements
Relevant prior knowledge
Meaningful material
Learner must choose to learn meaningfully

4. What is a Concept Map? Tool for organizing and representing knowledge
Directed Graph-based Knowledge Representation
Concepts
a perceived regularity in events or objects, or records of events or objects, designated by a label
Propositions (Linking Words)
statements about some object or event in the universe, either naturally occurring or constructed
contain two or more concepts connected with other words to form a sentence

5. An Example

6. Some Characteristics
Concepts are often structured in hierarchical fashion
Most general concepts arranged at the top and less general concepts arranged lower in the map
Knowledge is organized into domains
Use Cross-links to represent relationships between concepts crossing different domains. This helps us see how domain knowledge items are related to each other.

7. History of Concept Maps
Research program to sought children's understanding, based on learning psychology of David Ausubel(1963, 1968, 1978)
Ausubel’s idea: Learning takes place by the assimilation of new concepts and relationships into existing concept propositional frameworks held by the learner.
What is the origin of the first concept?
Children acquired this during the age of birth to three years when they identify regularities around them and begin to identify language levels or symbols for these regularities (Macnamara, 1982)

8. Types of Learning Reception learning: Discovery learning:
New meanings are obtained by asking questions to discover relationship between known and unknown.
Concepts attributes are described (by others) using language
Discovery learning:
With sufficient experience and prior knowledge, a learner may discover new knowledge independently.
Concepts’ attributes are identified autonomously by a learner

9. Reception Learning Rote learning:
Learning is basically memorization or saving knowledge so it can be used later.
Advantages:
No processing required.
Saves time?
Some AI programs use this technique
Disadvantages:
Knowledge retrieval is the problem

10. Reception Learning Meaningful learning: Advantages: Key:
Materials must be conceptually clear, presented with language and examples related to the learner’s prior knowledge.
Materials must relate new knowledge to prior knowledge.
Advantages:
Active learning: the learner interacts with environment and manipulate objects
Constructive learning: the learner must establish relationship between new knowledge and prior knowledge
Authentic learning: thoughts and ideas rely on the contexts in which they occur in order to have meaning
Key:
Intentional learning, learning depends on learners

11. Learning process
Understanding of learning by considering Human memory:

12. Constructing Concept Maps
Choose a segment of text or laboratory activity, or a particular question that you are trying to understand
Select concepts. Order them from most general to least general
Construct an arbitrary concept map
Use a computer software program for achieving greater flexibility. Inspiration is available in CS Lab (EB1036)

13. Constructing Concept Map
After preliminary map is constructed, it is usually a good idea to look for ways to improve the map.
Good concept maps are revised several (>=3) times.

14. Example: What is a plant?

15. A Bad Concept Map .

16. Another Example - Data Storage

17. Macro and Micro Concept Maps
Macro map:
Provides global view of a system.
Micro map:
Provides more specific view of the instructional program.
